VALVE-SPRING LIFTER.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed May 29, 1919. Serial No. 300,656.

To (ZZZ whom it may concern: ,Be it known that I, Ennn CHAuLns AUS- TIN, a citizen of the United, States, residing at lVahoo, in the county of Saunders and State of Nebraska, have invented certain new and useful Improvements in Valve- Spring Lifters, of which the following is a specification. 1

The object of this invention is'to provide a simple, inexpensive. and easily operated tool by the use of which the work of assembling or disassembling the parts of a valve in an internal combustion engine will be expedited. The invention is illustrated in the accompanying. drawings and will be hereinafterfully described, the novel features being subsequently pointed out in the appended claims.

In'the drawings Figure v1 is a perspective view of my improved tool n V Fig. 2 is an edge elevation of the upper portion of the tool; I v

F ig. 3 is a side elevation of the tool showing the manner of applying the same;

Fig. 4.- is a view showing the body and the .presse'r pivot or .pin in section; V

Fig. 5 is a horizontal section on the line .55 of Fig. 3;

Fig. 6 is a detail plan view of the foot;

Fig. 7 is an elevation of another form of the invention;

Fig. 8 is a perspective view of the upper portion of the tool shown in Fig. 7

In carrying out my invention, Iemploy a standard or supporting bar 1 which is pro vided with a lateral foot 2 adapted to engage around the stem of the valve and under the spring cap or collar thereon, the extremity of the foot being forked, as shown at 3, to facilitate such engagement. The standard is preferably constructed of two similar metallic bars welded or otherwise firmly secured together and having their lateral portions free of each other but normally lying close together, the fork 3 being formed by offsetting the extremities of the lateral foot members 2, as clearlv shown. A set bolt erably; constructed of a blank of sheet steel eration of the device.

doubled upon itself into substantially inverted U-shape and provided in its shoulder portion at one end with a recess or notch, as shown at G, to fit around the standard. Be-

tween the wings or side members of the body,

I place blocks 7 which are adapted to fit against the opposite edges of the standard, as shown most clearly in Figs. 4 and 5, and thereby serve as guides to maintain the proper relative position of the body-upon the standard during the adjustment and op- These blocks are secured permanently in position by rivets or similar fastenings S inserted through the sides of the body 5 and the ends of the blocks as will be readily understood. The lower edges of the body 5 are cut-away toward their free ends, as shown at 9, to accommodate the 'movement of a pivot 10 and a spacing pin 11 which are secured to and extend between the links 12 which are pivoted at their rear ends to the hand lever 13. The pivotal connection, 14, of the links and the said hand lever is disposed near the fulcrum of the lever which is inserted through the lever and lugs or ears 15 projecting from the body 5. The lever 13 is preferably constructed by rolling a block of sheet steel into the desired form so that the dead weight of the tool will be minimized. The pivot 10 at the front ends of the links 12 forms the pivotal connection between the members 16 bers 16 and mounted upon the pivot 10.

The lower end of the toggle member 17 is pivoted between. the sides of a U-shaped arm 19 which is fulcrumed, as at 20, between the sides of the body 5 at the lower edge thereof and carriesat its forward free end a presser pin 21 which is adapted to engage the body 22 of the valve. The pin 21 is secured rigidly at its upper end between the sides of the arm 19 and the free extremities of said sides. are bent toward each other, as shown'at 23, so as to effect a firm engagement with the pin and prevent twisting of the same.

The use of the device will, it is thought, be readily understood on reference to Fig. 3. hen it is desired to remove a valve from a motor, indicated. conventionally at 24, the

and

fork 3 is engaged under the spring cap or collar 25 with the handle 13 raised, as shown" in Fig. 4, in which position the toggle will be collapsed and the. presscr pin' 21' rela tively raised. The tool is then rocked about the point of engagement between the fork 3 and the valve stem 26 so as to bring the presser pin 21 into position over and bearing upon the valve body 22, after which the handle 13 is swung downwardly to the position shown in Fig. 3 which movement will cause the pin 21'to serve as a pivot or fulcrum upon which the body 5 and standard 1 will be caused to rise thereby compressing.

the work involved in fitting a valve in place or cleaning the. same or any of the parts adjacent thereto is thereby facilitated and time saved.

1 Mydevice is exceedingly simple in the constructionlrand arrangement of its parts and is very efl'ectlve when in use. The body '5 maybe moved along the standard 1', so as to accommodate the tool to valve stems of different lengths, and when 1t has been brought to the desired position upon the standard it may be secured in that position by a set screw or bolt 29 mounted in the upper end of 'theouter block 7 and. bearing against the standard as will be readily understood. The standard 1, the pin 21 and the toggle member 17 are illustrated as constructed from solid bodies of metal but all the other parts'or the device may be con- I structed from pressed sheet steel so that the tool will possess sullicient strength to withstand all strains to which it is subjected without being so cumbersome or heavy that it may not be easily handled. I prefer to employ hair metal i'or the standard and the 'presser pin 21, but the toggle member 17 may be of sheet material if so desired. The

blocks '7 are also shown as being oi. bar ma terial but they may be of sheet metalfor of other light construction without detracting from the usefulness or any of the advantages of the tool. A link 12'is disposed at each side of the body 5 so that the pull upon the toggle will be balanced and the spacer 11, interposed between the said links, counteractsanytendency of the same to bend at points between the toggle and the edge of the body. I 4 In Figs. 7 and 8 I have shown a somewhat simpler form of the invention which is particularly adapted for use in shops handling motors ofa single type'and all of the same dimensions. In this embodiment the ad justable body is omitted and the upper end of the standard 30 is provided with an integral lateral arm 31 to the extremityof which the upper toggle members 32 are pivoted. The arm 33 is pivoted to the stand-. ard, as'at 34:, but is otherwise the same in all respects as the arm 19 in-the previously described form. The presser pin 35 is identical with the pin 21 and the-lower toggle member 36 connects the arm with the upper toggle members. Thehandle or operating lever 37 is fulcrurnedfas at '38,to an ear or lug 39 on the standard and is connected by links. l0 with the toggle. 7

V
